Description

  The present invention relates to an oxygen concentrator that separates and generates oxygen from the air and an improvement in an inspection time determination method for the oxygen concentrator.

Various oxygen concentrators have been proposed that are used by patients with illness in the lungs to draw high-concentration oxygen. A part of the atmosphere is used to create compressed air using a compressor, and the compressed air is used for adsorption. There has been known a comparatively compact oxygen concentrator that feeds oxygen into the cylinder and causes the patient to ingest oxygen generated by adsorbing nitrogen to the adsorbent in the adsorption cylinder using a nasal cannula.
Since such an oxygen concentrator is composed of many mechanical parts and the like, there has been a risk of malfunction due to wear or the like when operated for a certain period of time. For this reason, in order to prevent the occurrence of this defective state, the time for maintenance has been determined.
The time for performing this maintenance was set to the accumulated time of the operation time of the oxygen concentrator as in Patent Document 1.

JP 2008-136658 A

  However, even if the operation time is short, the oxygen concentrator has a problem that, for example, when a certain period of time has elapsed from the start of use, the member is likely to be defective due to deterioration over time.

  Therefore, the present invention provides an oxygen concentrator and a method for determining the inspection time of an oxygen concentrator capable of notifying the necessity of inspection in relation to not only the operation time but also other indicators other than that. For the purpose.

  In the present invention, the above-described problem is an oxygen concentrator that generates oxygen, including a time measuring device and a display unit that displays various display information. And an integrated operating time information generating unit that generates integrated operating time information, and whether or not the integrated operating time information exceeds required inspection time information that is reference time information to be inspected. The required inspection time determination unit for determining, the total use period information generating unit for generating the total use period information based on the first operation start time information and the operation end time information of the oxygen concentrator, and the total use period information The total use period information determining unit required to determine whether or not the total use period required inspection information that is the reference period information to be determined, and the inspection time determination unit determines that the required inspection time information has been exceeded, And / or A required inspection information display determination unit that displays the required inspection information on the display unit when the total inspection usage period information determination unit determines that the total required inspection period usage information has been exceeded. This is achieved by an oxygen concentrator.

According to the said structure, it has an integrated operation time information production | generation part which accumulate | stores the operation time information of an oxygen concentrator in the operation time information before it, and produces | generates integration operation time information. For this reason, it is possible to obtain operating time information that is the actual usage time of the oxygen concentrator and integrated operating time information that is integrated information of these operating time information.
In addition, since the integrated operating time information has a required inspection time determination unit that determines whether or not the required operating time information, which is reference time information to be inspected, has been exceeded, is the time when the integrated operating time should be inspected? It can also be determined whether or not.

A total usage period information generating unit that generates total usage period information based on the first operation start time information and operation end time information of the oxygen concentrator, and the total usage period information is the reference period information to be inspected. A total usage period information determining unit that requires inspection to determine whether or not the total usage period information has been exceeded.
For this reason, the elapsed time since the oxygen concentrator was first operated can be acquired as the total usage period information, and it can also be determined whether or not this total usage period information is the time for the inspection. it can.

Furthermore, when the inspection time determination unit determines that the inspection time information has been exceeded and / or the inspection required total usage period information determination unit determines that the inspection total usage period information has been exceeded, the display unit requires the inspection information. And a necessary inspection information display determination unit.
For this reason, not only the accumulated operating time information that is the total of the actual operation time of the oxygen concentrator, but also the total usage time that is the elapsed time since the start of the operation of the oxygen concentrator component parts, etc. Judgment can also be made based on the period information, and the result can be displayed on the display unit to notify the user.
For this reason, the user of the oxygen concentrator can know that the inspection time has come by visually recognizing this display, and perform inspection, maintenance, and overhaul before the components of the apparatus are defective. be able to.
Such an oxygen concentrator is used to treat a patient's disease. For this reason, it is particularly important to appropriately perform an inspection or the like for accurately preventing the occurrence of the defect.
In this respect, according to the above-described configuration, it is possible to notify the user of an inspection or the like at an appropriate time, and therefore it is possible to prevent the occurrence of a defect in the oxygen concentrator and the like with extremely high accuracy.

  Preferably, the operating time information is changed based on the gas compressor that compresses the gas, the flow rate adjusting unit for changing the flow rate of the gas compressor, and the flow rate information adjusted by the flow rate adjusting unit.

According to the above configuration, the operating time information is changed based on the gas compressor for compressing the gas, the flow rate adjusting unit for changing the flow rate of the gas compressor, and the flow rate information adjusted by the flow rate adjusting unit. The operating time change information generating unit.
The oxygen concentrator varies depending on the flow rate of the gas compressor, and the possibility of occurrence of defects in the components and the like also changes. That is, for example, the larger the flow rate, the easier it is for defects to occur in a short time.
Therefore, in the above configuration, by changing the operation time information based on the magnitude of the flow information, for example, when the flow information is large, the operation time information passes faster than when the flow information is small. This makes it possible to prevent defects in the oxygen concentrator with higher accuracy.

  Preferably, the apparatus has a switch unit for operating or stopping the oxygen concentrator, and the operation time changes a plurality of times until the oxygen concentrator operates in the switch unit and the oxygen concentrator stops in the switch unit. The oxygen concentrator is characterized in that the information generator is operated.

According to the above configuration, the switch unit for operating or stopping the oxygen concentrator is provided, and the operation time is changed a plurality of times until the oxygen concentrator is operated at the switch unit and the oxygen concentrator is stopped at the switch unit. The information generating unit operates.
For this reason, for example, even if the user changes the flow rate during one operation of the oxygen concentrator (from when the switch is operated to when it is stopped), the operation time is changed according to the change. Information can be generated. For this reason, it can be judged whether it is time to test more accurately, and the defect of the oxygen concentrator can be prevented with higher accuracy.

  According to the present invention, the subject is a method for determining an examination time of an oxygen concentrator that generates oxygen, comprising a timing device and a display unit that displays various types of display information. The operation time information of the oxygen concentrator is added to the previous operation time information, and the integrated operation time information generation step for generating the integrated operation time information, and the inspection time determination unit requires the integrated operation time information, The required inspection time determination step for determining whether or not the required inspection time information, which is the reference time information to be inspected, has been exceeded, and the total use period information generation unit is configured to provide the first operation start time information and the operation end time of the oxygen concentrator.

Therefore, the oxygen concentrator 10 includes a main control CPU (Central Processing Unit) 22 shown in FIG. 3, a RAM (Random Access Memory) and a ROM (Read) not shown. Only Memory). For this reason, the main control CPU 22 is connected to the first storage unit 40 and the second storage unit 60 shown in FIG.
FIG. 4 is a schematic block diagram showing data and the like stored in the first storage unit 40, and FIG. 5 is a schematic block diagram showing data and the like stored in the second storage unit 60.
The first storage unit 40 and the second storage unit 60 shown in FIG. 3 to FIG. 5 are described separately for convenience of explanation, but do not indicate that the data is actually divided and stored in this way. Absent.

By the way, as shown in FIG. 3, the oxygen concentrator 10 has an air intake 22 for taking in air from the outside. The air taken in this way is compressed by a compressor 23 such as a compressor. The compressor 23 is connected to the motor 24 and is driven by the motor 24.
The compressed air compressed by the compressor 23 is alternately supplied to the first adsorption cylinder body 26a and the second adsorption cylinder body 26b via the two switching valves 25a and 25b (electromagnetic valves and three-way valves) shown in FIG. Will be supplied.

As shown in FIG. 3, the oxygen concentrator 10 includes a real-time calendar clock 30 that is a time measuring device, for example, and is connected to the main control CPU 22.

FIG. 6 is a schematic flowchart of main operations and the like showing an inspection time determination method and the like of the oxygen concentrator 10 according to the present embodiment.
Hereinafter, along with the flowchart of FIG. 6, the configuration of FIGS. 4 and 5 and the like will be described while explaining the operation and the like of the test time determination method of the oxygen concentrator 10.

First, when the user operates the power switch 14 shown in FIGS. 1 to 3 to use the oxygen concentrator 10 of FIG. 1, the operation start date register is set to “ 0, that is, whether or not unregistered is determined.
Specifically, the operation start date determination unit (program) 41 in FIG. 4 operates to determine whether or not operation start date data has already been registered in the operation start date register 61 in FIG.
If the operation start date data is not registered in the operation start date register 61 in ST1, the process proceeds to ST2 and the date of the real-time calendar clock 30 in FIG. This date is an example of the first operation start time information.
Thus, by registering the date of the real-time calendar clock 30 in the operation start date register 61, the user's start date can be recorded reliably.

Next, in ST3, the time data of the real-time calendar clock is registered as start time data. Specifically, the time data acquisition unit (program) 42 of FIG. 4 operates and registers the time of the real-time calendar clock 30 of FIG. 3 in the start time data register 62 of FIG.
Next, it progresses to ST4 and acquires the setting flow volume data of the said apparatus. The flow rate that is the amount of compressed air of the compressor 23 of the oxygen concentrator 10 can be changed by the oxygen flow rate setting button 16 of FIG. 3 as described above. Therefore, the oxygen flow rate data changed by the user or the like is registered in the set flow rate data register 63 of FIG.
Specifically, when the user or the like operates the oxygen flow rate setting button 16, the set flow rate acquisition unit (program) 43 in FIG. 4 operates, and the oxygen flow rate data changed by the operation becomes the set flow rate in FIG. Registered in the data register 63.

Next, the process proceeds to ST5. In ST5, it is determined whether or not the set flow rate is 2.5L or more. Specifically, the acceleration coefficient determination unit (program) 44 in FIG. 4 operates and refers to the oxygen flow rate data in the set flow rate data register 63 in FIG. 5 to determine whether the oxygen flow rate data is 2.5 L or more. .
If the oxygen flow rate data in ST5 is 2.5L or more, the process proceeds to ST6, and if it is less than 2.5L, the process proceeds to ST7.
In ST6, the acceleration coefficient is set to “1.6”, and in ST7, the acceleration coefficient is set to “1.0”.

Specifically, the acceleration coefficient determination unit (program) 42 stores data stored in the acceleration coefficient determination data register 64 of FIG. 5 (when the set flow rate is 2.5 L or more, the acceleration coefficient is 1.6, In the case of less than 2.5L, the judgment is made with reference to the acceleration coefficient 1.0).
In ST8, acceleration coefficient data is registered. Specifically, the acceleration coefficient (for example, “1.0” or “1.6”) determined by the acceleration coefficient determination unit (program) 42 is registered in the acceleration coefficient data register 65 of FIG.

Next, the process proceeds to ST9. In ST9, it is determined whether 15 minutes have passed.
Specifically, the time lapse determination unit (program) 45 in FIG. 4 operates and refers to the start time data in the start time data register 62 in FIG. 5, the elapsed time data register 66, and the real-time calendar clock 30 in FIG. In comparison with the value registered in the elapsed time data register 66, for example, it is determined whether or not 15 minutes have elapsed.

If it is determined in ST9 that 15 minutes have passed, the process proceeds to ST10. In ST10, the time data in the elapsed time register 66 is multiplied by the acceleration coefficient data ("1.0" or "1.6") in the acceleration coefficient data register 65 in FIG. Register in the data register 67.
Specifically, the accumulated time data generation unit (program) 46 shown in FIG. 4 operates to refer to the elapsed time data in the elapsed time data register 66 and the acceleration coefficient data in the acceleration coefficient data register 65 in FIG. The time data is multiplied by the acceleration coefficient data to obtain the accumulated time data, which is registered in the accumulated time data register 67 of FIG.

Next, in ST11, the accumulated time data is added to the registered overhaul time data, and the overhaul time data is updated.
Specifically, the overhaul time generation unit (program) 47 in FIG. 4 operates and adds the accumulated time data in the accumulated time data register 67 to the overhaul time data registered in the overhaul time register 68 in FIG. Update overhaul data.
Therefore, the accumulated time data is an example of operating time information, and the accumulated time data generating unit (program) 46 is an example of an operating time change information generating unit. The overhaul time register 68 is an example of accumulated operating time information, and the overhaul time generating unit (program) 47 is an example of an accumulated operating time information generating unit.

Thus, in ST11, overhaul time data that is the accumulated use time of the oxygen concentrator 10 can be registered in the overhaul time register 68.
Next, in ST12, the time data of the real-time calendar clock 30 is registered as end time data.
Specifically, the time data acquisition unit (program) 42 of FIG. 4 operates to acquire the time data of the real-time calendar clock 30, and this time data is stored in the end time data register 69 of FIG. Register as
This end time data is an example of the operation end time information.

  Next, in ST13, difference data between the operation start date data and the end time data is obtained. Specifically, the operation start date reference overhaul determination unit (program) 48 operates and refers to the operation start data and end time data register 69 of the operation start date data register 61 in FIG.

Next, in ST14, it is determined whether or not this difference data is 1035 days or more. Specifically, the operation start date reference overhaul determination unit (program) 48 of FIG. 4 operates, and the data registered in the operation start date reference overhaul reference period data register 70 of FIG. Refer to and judge.
This difference data is an example of the total usage period information, and the operation start date reference overhaul determination unit (program) 48 is an example of the total usage period information generation unit.
Note that the oxygen concentrator 10 may deteriorate over time due to a certain period of time, for example, about 1035 days after the actual usage time, thereby causing defects.
Therefore, in the present embodiment, it is determined to perform overhaul or the like on the basis of 1,035 days on which a certain deterioration with time may occur.
Therefore, the operation start date reference overhaul reference period data is an example of the total use period information required for inspection, and the operation start date reference overhaul determination unit (program) 48 is an example of the total use period information determination unit required for inspection.
In the present embodiment, the operation start date reference overhaul reference period data is a single period of, for example, 1035 days. However, the present invention is not limited to this, and different periods may be set depending on the model of the oxygen concentrator 10.
With this configuration, the overhaul time can be notified to the user and the like more appropriately, and the occurrence of malfunctions and the like of the components of the apparatus 10 can be prevented in advance.

If the difference data is 1035 days or more in ST14, it is determined that there is a possibility of deterioration over time, and in ST15, “overhaul” is displayed on the alarm display unit 20 in FIG.
Therefore, when the user who sees this “overhaul” display performs overhaul, it is possible to prevent the occurrence of defects due to deterioration with time of the components of the oxygen concentrator 10.
Specifically, in ST15, the operation start date reference overhaul determination unit (program) 48 operates, and the characters “overhaul” are displayed on the alarm display unit 20 in FIGS.
As described above, “overhaul” is an example of the inspection required information, and the operation start date reference overhaul determination unit (program) 48 is an example of the inspection required information display determination unit.

On the other hand, if the difference data is less than 1,035 days in ST14, the process proceeds to ST16. In ST16, it is determined whether or not the overhaul time data in the overhaul time register 68 exceeds 14,500 hours.
Specifically, the overhaul register value determination unit (program) 49 in FIG. 4 operates, and the overhaul time reference data of the overhaul time register 68 in FIG. 5 is registered in the overhaul register reference value data register 71. It is determined whether data (for example, 14,500 hours) has been exceeded.

When the actual operation time exceeds a certain period, for example, 14,500 hours, the oxygen concentrator 10 may cause malfunction due to wear of its components and the like. Therefore, in the present embodiment, when the overhaul data exceeds 14,500 hours, that is, when the cumulative total of the actual use time of the oxygen concentrator 10 exceeds 14,500 hours, this operation is performed. In order to prevent the occurrence of defects, it is determined that overhaul should be performed.
The overhaul register reference value data is an example of the inspection time required information, and the overhaul register value determination unit (program) 49 is an example of the inspection time determination unit.

  In ST16, if the overhaul time data exceeds 14,500 hours, the process proceeds to ST15, and “Overhaul” is displayed on the alarm display unit 20 as described above, and the necessity is notified to the user or the like. It is the composition to do.

In the present embodiment, as described above, when generating the accumulated time data serving as a reference for generating the overhaul time data, the larger the amount of oxygen flow, the longer the time is passed ( ST4 to ST8).
Usually, as the oxygen flow rate increases, defects in the oxygen concentrator 10 are more likely to occur. Therefore, when the flow rate is high, the acceleration coefficient is set to 1.6 and the overhaul is executed earlier.

As described above, in this embodiment, the oxygen concentrator 10 used for disease treatment or the like is a device that is not allowed to generate malfunctions or the like as much as possible. For this reason, in the present embodiment, the timing of the overhaul is determined not only by the cumulative operation time when the apparatus 10 is actually used, but also by the passage of time since the operation of the apparatus 10 is started. .
For this reason, it is possible to notify the user or the like of the overhaul time with higher accuracy, and to prevent the occurrence of malfunction of the components of the apparatus 10 in advance.

By the way, in ST16, when the overhaul register value does not exceed 14,500 hours, the overhaul display is not executed because it is not the time of overhaul yet.
Then, the process proceeds to ST17, where it is determined whether or not the power switch 14 is turned off (OFF).

On the other hand, in ST17, when the power switch 14 is ON, the processes after ST3 are repeated.
In particular, by repeating the operations from ST3 to ST11, the change in the oxygen flow rate can be grasped more precisely, and the acceleration coefficient can also be changed precisely corresponding to the change in the oxygen flow rate.
As described above, in the present embodiment, if the switch is in the ON state, that is, the oxygen concentrating device 10 is in the operating state, the acceleration coefficient data is acquired a plurality of times, so that the overhaul time can be determined very accurately.

The present invention is not limited to the embodiments described above.
In the present embodiment, when the difference data (elapsed time from the operation start date) exceeds the reference value (1,035 days), the overhaul register value (cumulative operation time) is not determined. ing.
However, the present invention is not limited to this, and a configuration may be adopted in which the overhaul register value is determined first, and when this value exceeds the reference value (14,500 hours), the difference data is not determined. Furthermore, an overhaul display may be performed only when both reference values exceed.
